mismatch between wrong uri in jsp tlds (embedded in jsp( and the standard.jar/jstl.jar version you implemented in webapp's /WEB-INF/lib Follow these steps exactly: 1. If you like, download the latest standard.jar from http://www.apache.org/dist/jakarta/taglibs/standard/jakarta-taglibs-standard-current.zip or goto step 4 2. Unzip it 3. Copy the standard.jar and jstl.jar file into WEB-INF/lib directory in you project 4. Open standard.jar with say winzip 5. Find *.tld files 6. Note all the *.tld files 7. In the WEB-INF directory, delete all the *.tld files already in standard.jar. You don't need them in WEB-INF. Also remove the <taglib>blah blah blah </taglib> of these *.tld files. For example: <taglib> <taglib-uri>http://java.sun.com/jsf/core</taglib-uri> <taglib-location>/WEB-INF/c.tld</taglib-location> </taglib> 8. Assume standard.jar is still open in winzip, open say c.ltd, and you would find: <?xml version="1.0" encoding="UTF-8" ?> <taglib xmlns="http://java.sun.com/xml/ns/j2ee"; xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"; xsi:schemaLocation="http://java.sun.com/xml/ns/j2ee web-jsptaglibrary_2_0.xsd" version="2.0"> <description>JSTL 1.1 core library</description> <display-name>JSTL core</display-name> <tlib-version>1.1</tlib-version> <short-name>c</short-name> <uri>http://java.sun.com/jsp/jstl/core</uri> <validator> so and so... </taglib> 8. Notice the <uri>, it is different from http://java.sun.com/jstl/core in step 1. This is the problem. You need to use <%@ taglib prefix="c" uri="http://java.sun.com/jsp/jstl/core"; %> and not <%@ taglib prefix="c" uri="http://java.sun.com/jstl/core"; %> If you havn't noticed the difference - its the addition of "jsp/" HTH Martin ______________________________________________ Disclaimer and confidentiality note Everything in this e-mail and any attachments relates to the official business of Sender.
